a)Advantages
Usually the pages in a website have the same type of content which has to be reloaded every time a request is made if we used the classical methods. Things improve when we use Ajax because only the content that requires updating will be sucessed . This will mean less loading time and less used bandwidth. The user interface will become more interactive and the section of web pages will become reloadable each alone all this due to asynchronous request usage.
b)Disadvantages
We could not be able to use the back button of the browser to see the last Ajax based page, however we will see the last before the Ajax based one, this is because when we use successive Ajax requests for building dynamic web these requests don’t register automatically in the history of the browser. For many changes in the history we can use invisible Frames. Also bookmarking a specific state of dynamic updates of a page. Using JavaScript stops crowers from indexing a page and different other methods have to be used, and if a browser is not JavaScript or Ajax compatible or it has them deactivated will not use this alternative. The same mobile phones or other mobile devices can’t read JavaScript pages or don’t display the content in a dynamic way.
